In C Algorithms for Real-Time DSP, author Paul M. Embree presents a complete guide to digital signal processing techniques in the C programming language. This book is structured in such a way that it will be most useful to the engineer who is familiar with DSP and the C language, but who is not necessarily an expert in both. All of the example programs in this book have been tested using standard C compilers in the UNIX and MS-DOS programming environments. In addition, the examples have been compiled using the real-time programing tools of specific real-time embedded DSP microprocessors (Analog Devices ADSP-21020 and ADSP-21062 Texas Instruments TMS320C30 and TMS320C40 and AT&T DSP32C) and then tested with real-time hardware using real-world signals.

Rotating shafts experience a an elliptical motion called whirl. It is important to decompose this motion into a forward and backward whil orbits. The current function makes use of two sensors to generate a bi-directional spectrogram. The method can be extended to any time-frequency distribution
